Title: Improved Process for the Manufacture of Sulphuric Acid from Sulphate of Lime.
Inventor: LUCIEN PAUL BASSET
IPC: C01B17/74
Filed: 1917-06-22
Abstract: 124,842. Basset, L. P. June 22, 1916, [Convention date]. Void [Published under Sect. 91 of the Act]. Sulphuric acid; ammonium sulphate and phosphate; ammonia; metaphosphoric acid. - Sulphurio acid is obtained from calcium sulphate by a series of operations in which ammonium sulphate is first prepared, and this is then treated to obtain ammonia and sulphuric acid by alternative methods. The calcium sulphate is treated with ammonia and carbonic acid to obtain ammonium sulphate, and this is then heated with an oxide, such as iron or chromium oxide, or a mixture of oxides, or with an alkali sulphate, ammonia being liberated and used again, and a residue of metal sulphate or alkali bisulphate remaining, from which sulphuric acid is recovered by further heating. An alkaline-earth sulphate may be mixed with the alkali bisulphate to facilitate its decomposition. Alternatively, the ammonium sulphate may be heated with metaphosphoric acid, when sulphuric acid is expelled and ammonium metaphosphate NH4HP2O6 is formed, which, on further heating, yields ammonia and metaphosphoric acid. The calcium sulphate is mixed with water in a mixer a and passed to tanks b<1>, b<2>, b<3>, which are used successively to supply a tower c into which ammonia and carbonic acid are led by pipes h, i, the gas escaping at j being led to an acid washer to recover remaining ammonia. The liquor is circulated between the tower e and tank b<1> until the reaction is finished, whereupon it is discharged to a filter l, and the next tank b<2> is used to supply the tower. The ammonium sulphate solution is collected in a tank m and passed to a drier n, the solid salt, together with iron oxide from a feed r, being led to a heater s The wash-waters of the calcium carbonate in the filter l are collected in a tank o and led back to the tank a for mixing with the next charge of calcium sulphate. The ferric sulphate discharged from the heater s is decomposed in a suitable furnace, for instance a furnace similar to a lime-kiln heated by an oxidizing-flame, or a mechanical furnace, of the kind used for roasting pyrites, the material passing downwards from floor to floor, being directly heated by oxidizing- gases; or the ferric sulphate may be heated in a closed vessel.

Title: Printing press
IPC: B41F1/26
Filed: 1948-04-06
Abstract: 666,969. Printing-machines. CHANDLER & PRICE CO. April 6, 1948 [April 23, 1947], No. 9589/48. Class 100 (ii). In a platen printing-machine of the kind in which a curved platen 8 is used, the type forme 18 is so mounted on the oscillating frame 3 that it is capable of limited oscillatory and translatory movement with respect thereto in order to effect accurate register between the platen and type forme during printing. The oscillating frame 3 is operated by a crank-pin 22 and links 20, and the platen 8 is mounted in a fixed frame and is moved to the position shown in Fig. 1 to receive the sheets, the bed 17 which carries the forme 18 being mounted in its frame 28 by means of ears 26 which are slotted to receive rollers 29 on the sides 28 of the frame and so permit longitudinal movement of the bed relatively to its frame, and slotted ears 30 at each side of the bed engage rollers 32 on side members of the frame and so permit of angular movement against the action of springs 35 which normally maintain the bed 17 in such position that the right hand ends of the slots 31 engage the rollers as shown in Fig. 1. When the parts are moved to the position shown in Fig. 2 the printing operation is about to begin and the crank 22 is approaching dead-centre. To secure a true rolling motion between the forme 18 and the platen, the bed is controlled in its movements by means of levers 40, which are carried by the frame 3 and oscillated by a cam 47 on the shaft 10 of the driving gear 9 through a lever 41. Rollers 44 on the levers 40 engage the sloping sides 34 of the lugs and the bed 17 is thus given a counterclockwise movement about the rollers 29 and can also move vertically relatively to the rollers. The printing operation tends to move the bed in a contrary direction and this is controlled by the pressure of the rollers 44 against the cam sides 34. The direction and amount of movement of the bed 17 is controlled by the floating mountings consisting of the pin-and-slot connections 27, 29, 31, 32, which are arranged so as to maintain true registry in all positions. Specifications 14805/05, [Class 100], 174,445, [Class 100 (ii)], and 639,664 are referred to.

Filed: 1947-04-11
Abstract: 628,866. Frequency and phase-difference measurements. PHILIPS LAMPS, Ltd. April 11, 1947, No. 9690. Convention date, Sept. 2, 1944. [Class 37] [Also in Group XL (c)] In a mixing circuit oscillations are applied to the grid of a valve and are modulated by a train of short pulses applied to the anode, which is so biassed that conduction occurs only during the pulsing period. The combination frequencies formed between the oscillations and the harmonic series into which the pulse train resolves include a term due to the harmonic nearest in frequency to the oscillations, and this is selected by means of a low-pass filter 11, 12 cutting off at half the fundamental frequency of the pulse train. According to the Specification as open to inspection under Sect. 91 the arrangement may be used for frequency measurement, the oscillations applied to the grid comprising the unknown frequency and the output from the low-pass filter being measured by known means, such as comparison with a low-frequency oscillator. It may also be used for measuring the relative phase of oscillations where frequency coincides with one of the harmonics of the pulse train by measurement of the D.C. voltage produced across the condenser 12. A modification of the arrangement (Fig. 1, Cancelled, not shown) may also be employed for generating a continuous range of frequencies (see Group XL (c)). This subject-matter does not appear in the Specification as accepted.
